I have one (the OG big one, not the new Impact version.)
It's a pretty cool device for its price (it's the only decent alternative to a Roland drum machine, whose sound I loathe, in this range of price) but it could have been better. I mean, it's built like a tank, it's really easy and intuitive to use I think, and it's made for performance and live use, no submenus or any kind of hidden functions that are a pain to find or activate. It does however lack a bit of personality and bite soundwise (and the snare tends to sound lower than most of the other sounds when the volumes are at the same levels), and I wish the pads responded better at times. But it's a really cool machine for its price and I tend to use mine through a compressor and a homemade fuzz+blend pedal. It sounds alright.
I did decide last year to not buy any Arturia products anymore though, mostly because they sell unfinished products. I'm pretty certain my Keystep is faulty, the sound volumes on the Drumbrute can be uneven, I saw lights blinking when going through presets on a Matrixbrute whereas they shouldn't do so, etc... I'm done with them.
